-## usb_detach.c
-
-When trying to flash on Linux, you may encounter a "Resource Unavailable" error. This means that Linux's HID driver has taken exclusive control of the keyboard, and the program script can't flash it.
-This program can force Linux to give up a device, so that the programming script can reset it.
-
-### To compile:
-```
-gcc usb_detach.c -o usb_detach
-```
-
-### To run:
-1. Use `lsusb` to discover the Bus and Device numbers for your keyboard.
-2. Run the program: `sudo ./usb_detach /dev/bus/usb/<BUS>/<DEVICE>`.
-3. Build and program the firmware as normal.
